Lily plant named &#39;Corso&#39;

ABSTRACT

A new and distinct cultivar of Lily plant named ‘Corso’ characterized by its large erected flowers with long petals and curly edges, soft red-purple color with contrasting yellow/green mid-vein, vigorous growth and long lasting quality.

BACKGROUND OF THE INVENTION

[0001] The present invention comprises a new and distinct cultivar of lily plant, botanically known as Lilium L., and hereinafter referred to by the cultivar name ‘Corso’.

[0002] ‘Corso’ is a product of a planned breeding program which had the objective of creating new lily cultivars having large erected flowers and vigorous growth.

[0003] ‘Corso’ was originated from a hybridization made by the inventor in a controlled breeding program in Rijnsburg, the Netherlands in 1993. The male and female parents were unnamed seedlings of Lilium L. oriental hybrids. Both parents are proprietary cultivars used in the breeding program.

[0004] ‘Corso’ was discovered and selected as one flowering plant within the progeny of the stated cross by the inventor, Cees A. van der Voort, in May 1993 in a controlled environment in Rijnsburg, the Netherlands.

[0005] The first act of asexual reproduction of ‘Corso’ was accomplished when scales were taken from the initial selection in October 1995 in a controlled environment in Rijnsburg, the Netherlands by, or under the supervision of, Cees A. van der Voort. Horticultural examination of selected units initiated in May, 1995 has demonstrated that the combination of characteristics as herein disclosed for ‘Corso’ are firmly fixed and are retained through successive generations of asexual reproduction.

BRIEF DESCRIPTION OF THE INVENTION

[0006] The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Corso’ which in combination distinguish this lily as a new and distinct cultivar:

[0007] 1. large, erect flowers;

[0008] 2. slim tepals with curled edges;

[0009] 3. intense pink color with contrasting yellow-green mid-vein; and

[0010] 4. vigorous growth habit.

[0011] ‘Corso’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity, and daylength without any change in genotype. The following observations, measurements, and comparisons describe plants grown in the experimental research station CPRO-DLO, Wageningen, the Netherlands under conditions which approximate those generally used in commercial practice.

[0012] Of the many commercial cultivars known to the present inventor, no other cultivars are similar in comparison to ‘Corso’.

BRIEF DESCRIPTION OF THE DRAWING

[0013] The accompanying color photographic illustration shows typical plant and flower characteristics of ‘Corso’, with colors being as true as possible with illustrations of this type.
